Set-up Presentation • Sources of comments • General comments on Transparency • General comments on Conservativeness • Comments on Transparency & Conservativeness in calculations
Sources of Comments • Lucio Pedroni, Cati • Bernhard Shclamadinger • Robert Seaton, Brinkman & Associates reforestation Ltd. • Federal University of Paraná & Instituto Ecoplan (Brasil)
General comments on Transparency There is no scenario of possible land-cover sketched; SO NO SOUND ARGUMENTATION FOR THE BASELINE SCENARIO CHOSEN Policy, social, economic and environmental issues are considered fixed; IT IS NOT EXPLAINED WHY THIS IS LIKELY Project boundary NOT CLEARLY DEFINED
General comments on Conservativeness DIFFICULT TO ASSESS, because re-calculation of the derived figures is difficult THROUGH LACK OF TRANSPARANCY
Calculation total vegetative biomass • Biomass live trees • Biomass dead standing trees • Biomass of dead fallen trees • Shrub and herb biomass • Biomass of roots • Biomass of forest fuels (litter) + • TOTAL VEGETATIVE BIOMASS
Calculation total vegetative biomass • Biomass live trees • Biomass dead standing trees • Biomass of dead fallen trees • Shrub and herb biomass • Biomass of roots • Biomass of forest fuels (litter) + • TOTAL VEGETATIVE BIOMASS
Biomass live trees = 0, 1184 DAP 2,53(later replaced by allometric destructive sampling) COMMENTS ON TRANSPARANCY: Source of equation is missing Point of time of replacing this equation with allometric destructive sampling is missing
Calculation total vegetative biomass • Biomass live trees • Biomass dead standing trees • Biomass of dead fallen trees • Shrub and herb biomass • Biomass of roots • Biomass of forest fuels (litter) + • TOTAL VEGETATIVE BIOMASS
Biomass dead standing trees = Biomass living trees = 0,1184 DAP 2,53 COMMENTS ON CONSERVATIVENESS: Biomass dead standing trees should be corrected for density loss, for instance using “Machete test”
Calculation total vegetative biomass • Biomass live trees • Biomass dead standing trees • Biomass of dead fallen trees • Shrub and herb biomass • Biomass of roots • Biomass of forest fuels (litter) + • TOTAL VEGETATIVE BIOMASS
Biomass dead fallen trees = 0,4 DAP 2 L0,25 COMMENTS ON CONSERVATIVENESS: 0,4 Should be adjusted for density class doing “Machete test”
Calculation total vegetative biomass • Biomass live trees • Biomass dead standing trees • Biomass of dead fallen trees • Shrub and herb biomass • Biomass of roots • Biomass of forest fuels (litter) + • TOTAL VEGETATIVE BIOMASS
Biomass of roots = exp[-1,085 + 0,926 ln(total biomass of trees and shrubs)] ** Caims et al, 1997 COMMENTS ON CONSERVATIVENESS: Only biomass of roots of living trees should be calculated COMMENTS ON TRANSPARENCY: The source of this equation is not stated correctly, it should be: Cairns et al, 1997
Calculation of carbon total vegetative biomass =total vegetative biomass * 0.45 COMMENTS ON CONSERVATIVENESS: Conservative; IPCC-guidelines default value is 0.5
